Abstract

The invention discloses waterproof mortar for building and a preparation method of the waterproof mortar, relates to the field of building materials, and solves the problem that a waterproof materialin the prior art is easy to crack and poor in impermeability. According to the technical scheme, the waterproof mortar for building is prepared by taking a polymer emulsion as the main body and takingcement as a gel material through mixing and stirring with quartz powder and an auxiliary agent by adding clean water. The preparation method of the waterproof mortar for building comprises the following steps that S1, the polymer emulsion, water and an auxiliary agent are uniformly mixed in proportion to obtain a liquid material; S2, the cement and the quartz powder are uniformly mixed in proportion to obtain a powder material; S3, the liquid material and the powder material are uniformly stirred to obtain the waterproof mortar. Compared with a conventional waterproof material, the waterproofmortar has a good bonding property with cement, and the elasticity of the polymer emulsion also improves the crack resistance of the waterproof mortar, thereby improving the penetration resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a waterproof mortar for building and a configuration method thereof. Background technique [0002] With the improvement of people's requirements for the quality of construction projects and the use of buildings, the waterproofing of walls, waterproofing of wet interfaces, and waterproofing of basements has attracted more and more attention and attention from the construction industry. In the traditional waterproof concept, people often use flexible waterproof materials such as coiled materials, sheets, and coatings as independent waterproof materials in engineering. These flexible waterproof materials have strong ability to adapt to the deformation of the base layer and are convenient for large-scale construction. The degree of dryness of the base layer is relatively high, and the moisture content is generally required to be below 9%, which is difficult to achieve for undergroun...
